Make assets relative to URL
Assets are using absolute paths, which breaks some reverse proxy configs.
A quick fix would be to load the JS via js/... here https://git.rip/RemixDev/deemix-webui/-/blob/main/public/index.html#L24
Replaced ../../fonts with fonts/ within https://git.rip/RemixDev/deemix-webui/-/blob/main/src/styles/vendor/OpenSans.css and https://git.rip/RemixDev/deemix-webui/-/blob/main/src/styles/vendor/material-icons.css
